One interactive lab folds the whole of Topic 6 into a single experience: automated systems and the sensor–microprocessor–actuator loop, robotics and the characteristics of a robot, where robots are used and the trade-offs, and artificial intelligence with machine learning and expert systems. It teaches each idea, lets you drill it, then tests you — work straight through, or jump to the part you need.
Automated systems and the sensor → microprocessor → actuator loop, the three characteristics of a robot, where robots are used and their trade-offs, and artificial intelligence — machine learning and expert systems — in the exact mark-scheme wording.
